国内油田酸化用胶凝剂研究进展

Research progress of gelling agent for oilfield acidification

在酸化施工过程中,酸岩反应速度快、酸液有效作用距离短,会导致增产措施效果变差。现阶段国内解决该问题的方法是向酸液中加入胶凝剂来增加其缓速性能。总结了应用于酸化施工中的四类油田酸化用胶凝剂产品的基本组成及其性能,讨论了未来胶凝剂的发展趋势,为国内酸化施工提供了有效方法和依据。

Fast speed of acid-rock reaction and short effective distance of acidizing fluid, lead to worse stimulation effect on the acidification construction. To summarize and analyze both foreign and domestic treatment, namely the method of add to the gelling agent in acid to improve the retarding performance. In this paper, the basic composition and properties of four main gelling agents used at home and abroad were summarized, and discussed the development trends of gelling agents in future. This craft provides approaches and basis for domestic oilfield enterprises in acidification construction.
